Understanding the Basics of a Pyramid

A pyramid is a three-dimensional shape with a square base and four triangular faces that meet at the apex. The base area of a pyramid is the area of the square base, while the height is the perpendicular distance from the base to the apex. In this article, we will focus on calculating the volume of a pyramid given its base area and height.

The Formula for the Volume of a Pyramid

The formula for the volume of a pyramid is:

V = (1/3) * B * h

where V is the volume, B is the base area, and h is the height. This formula is derived from the fact that the volume of a pyramid is one-third the volume of a prism with the same base area and height.

Given Values and Calculations

We are given the base area of the pyramid as $$28 , \text{cm}^2$$ and the height as $24.9 \, \text{cm}$ . To calculate the volume, we can plug these values into the formula:

V = (1/3) * 28 * 24.9

Solving for the Volume

To solve for the volume, we need to multiply the base area by the height and then divide by 3.

V = (1/3) * 28 * 24.9 V = (1/3) * 697.2 V = 232.4

Conclusion

Therefore, the volume of the pyramid is $232.4 \, \text{cm}^3$ .
